Abstract
A composition comprising a coprecipitated magnesia-lanthana-alumina (MgO--La.sub.2 O.sub.3 --Al.sub.2 O.sub.3) wherein the MgO component is present as microcrystalline phase, having a BET (N.sub.2) surface area of at least 130 m.sup.2 /g, preferably part of which contains a catalytic oxidation and/or reducing promoter metal such as ceria, vanadia, iron and/or titania, is combined with an FCC catalyst which is used to catalytically crack a hydrocarbon feedstock that contains metal and/or sulfur.
